Got a couple of hours of Marine campaign and some MP matches last night and I'm feeling pretty blown away. The tension is amazing as the Marine (online Survivor is hilariously frantic) and the species DM I got into as a Predator was awesome, nice jungle map with some treetops to perch on and pick folk off, really empowering!
Can see why the graphics have been criticized, they're more polished than in the demo but aren't up to the best the 360 can offer. I'm not sure why they need to be though, movies don't get panned because they don't have Hollywood production values, surely there's room for games that don't all look as good as Gears 2?! I mean if we applied the same attitude to movies, say if special effects looked a bit duff, the genre never would have got off the ground.
Radiator, I'll add your tag at some point, hopefully catch you for a game sometime (I'm Superbeasto)!
